DDTC114WKA-7-F

Overview

The DDTC114WKA-7-F is a single NPN digital transistor manufactured by Diodes Incorporated, belonging to the DDTC114W series. It features an integrated pre-bias configuration with a typical base resistor of 10 kOhms and an emitter resistor of 4.7 kOhms, resulting in a resistance ratio of approximately 2.128. The device is housed in a compact SC-59 (SOT-23) surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates NPN epitaxial planar transistor with built-in biasing resistors for simplified circuit design.
• Provides a small PCB footprint through the SC-59 surface-mount package construction.
• Eliminates external resistor components, reducing assembly complexity and board space requirements.

Applications

• General-purpose switching applications in consumer electronics.
• Driver circuits for low-current loads in portable devices.
• Logic level shifting and interface buffering between microcontrollers and peripherals.

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distribution channels. Confirm RoHS compliance status and manufacturing date codes against current datasheet revisions. Ensure storage conditions adhere to moisture sensitivity level guidelines to prevent package damage prior to soldering.

Selection Notes

Select this component when a single NPN digital transistor with 10k/4.7k internal biasing is required. Verify that the 50V voltage rating and 100mA current capacity meet the specific load requirements. Consider the SC-59 package dimensions for PCB layout constraints compared to alternative packages like SOT-323.

Part Context

This part belongs to the DDTC114W family of pre-biased transistors from Diodes Incorporated. The 'W' suffix typically denotes the SC-59/SOT-23 package style, while 'KA' specifies the 10k/4.7k resistor combination. This series is designed to replace discrete resistor-transistor networks in modern electronic designs.

Replacement Considerations

Direct substitutes may include DDTC114WCA-7-F or DDTC114YKA-7 if package compatibility is maintained. Verify equivalent electrical parameters such as hFE and resistor tolerances before substitution. Cross-reference with other manufacturers' equivalents like Nexperia PDTC114YK only after confirming pinout and specification alignment.
